You can get a hub with isolation:

thanks a lot, if nearly fits the bill but it does not work for USB 2.0 but only USB1.1, does anyone know something that work for USB2.0?

Thanks in advance

Do you realize that anything that is USB 1.1 conforming and works at full speed? A USB 1.1 hub will work with USB 2.0 host and device at full speed, just not high speed.

yes I do realize but my app needs high speed transfer to work correctly so a USB1.1 isolation is not enough for the application to work properly...

It is a common misconception to think that saying USB 2.0 is the same as saying USB High Speed. It may be true that USB 1.0 and 1.1 did not have High Speed and that USB 2.0 does have high speed, but USB 2.0 also has Low Speed and Full Speed. So saying USB 2.0 says nothing about the speed.

If you need High Speed, you should say USB High Speed. It is the USB

Take a look at my first post, I told about High Speed...

-- "I need such product for USB high speed or at least USB full speed. " ^^^^^^^^^^^^^^^^^^^^^^^^^^^

It seems that USB 1.1 satisfies the "at least" part.

Pathetc.. you guys spent more time with etiquette and nitpciking than helping.

Who says we are here to help? Our purpose is to carp and fuss about foolish misuse of usenet, such as failure to snip (horrible example above) and lack of precision. The sacrifice of at least one rooster on the block is necessary before any help can be offered. Better results are had with sheep, and even better a bull. Without us all is chaos.

Appologies for the "lack of precision" with my cut paste in the .sig ... that was ugly.

As long as that is clear.

however, you will easily find worse offenders elsewhere.

I need USB high speed , but i'd really like to NOT say USB high speed , because it is unintuitive !!.

HIGH SPEED COMPARED TO WHAT ?!!!

Just more sales BS . Why do we let these Luddites create our language !!! This the proper way to say .............

Acoustic coupler has nothing to do with USBh/480 ... Please pay attention next time you post ....

I saw Samsungs EVAL Board ( ARM cpu , as in all PDAs ) and they wanted $1000 , now

$300 !! They show a 2.5" HDD attached in a 2nd photo ....

The ARM cpu will destroy the PC and Gates and Linus ....
